I've stumbled on a problem and realize that The E-Sylum is probably the best place to turn, and if you could run the pic with a plea for help I would be most
The coin is a 1696 Paris Mint Sol de 15 Deniers, popularly called a Recoined Sol in the English speaking world -- the recoined part because these were often struck over earlier
French douzains which were worth 12 Deniers. The recoining gave the French crown a 3 Deniers profit on each coin -- strike it with new dies and, voila, it's worth more money!
Unfortunately I cannot place the host coin that this one was struck over.
It is clearly dated 1622 (visible at the top obverse, directly above the 1696 date of the overstrike). There are sufficient legends on both sides from the host coin, especially
at the right reverse, that an attribution should be doable -- but not by someone with little expertise in world coinage like me! My first guess was one of the Swiss cantons, but
that doesn't seem to fit. Any help that the E-Sylum readers can give would be most appreciated! I should mention the host coin is struck in billon.
